A pump running at 1000 rpm consumes 1 kW and generates head of 10 m of...
For head
H2 = 40 m
For power,
P2 = 8 kW
H2 = 40 m
For power,
P2 = 8 kW

A pump running at 1000 rpm consumes 1 kW and generates head of 10 m of...
Given Data:
- Pump speed at 1000 rpm: Power = 1 kW, Head = 10 m
- Pump speed at 2000 rpm: ?
Calculation:
- Power Consumption (P) is directly proportional to the cube of the speed (N) of the pump. The formula is P2/P1 = (N2/N1)^3
- Power at 2000 rpm = (2000/1000)^3 * 1 kW = 8 kW
- Head generated by the pump is directly proportional to the square of the speed of the pump. The formula is H2/H1 = (N2/N1)^2
- Head at 2000 rpm = (2000/1000)^2 * 10 m = 40 m
Therefore, when the pump is operated at 2000 rpm, the power consumption would be 8 kW and the head generated would be 40 m of water, which corresponds to option 'D'.
